The SMBJ43CA with TVS SMB RoHS manufactured by Shikues is a bi-directional, transient voltage suppressor (TVS) diode. It is designed to protect sensitive electronics from high voltage, high power surges. This diode is compliant with Restriction of Hazardous Substances (RoHS) directives, which requires that electrical and electronic equipment not contain any of six hazardous materials. The device is a low capacitance, low-clamping voltage, rapid response, extremely low-leakage current and surge-protected diode. The SMBJ43CA can be used in power supplies, power distribution cabinets, industrial equipment, and automotive applications.
